Cropping an UIImage

Question

I\'ve got some code that resizes an image so I can get a scaled chunk of the center of the image - I use this to take a UIImage and return a small, square repre

Here's an updated Swift 3 version based on Noodles answer

func cropping(to rect: CGRect) -> UIImage? {

    if let cgCrop = cgImage?.cropping(to: rect) {
        return UIImage(cgImage: cgCrop)
    }
    else if let ciCrop = ciImage?.cropping(to: rect) {
        return UIImage(ciImage: ciCrop)
    }

    return nil
}
